I have a 1994 MAIII that shoots great. I'm wondering if the newer models , say 2000 on up are even better?
Any opinions?
Also how good are their longbows? Hand shock problems?

The newer MA's are a little heavier due to the amount of glass they now have in the risers, but shootability is the same in my opinion.

Their LB's perform very good for a LB without the ACS limb design.  
Widow advertise them to perform like their recurves, with a heavy arrow.  I think they're awful close to that performance, from my experience. No problem with handshock.

I LOOOOOOOVE my  Widow Longbows
